Of the remaining Conservative MPs, 127 were in favour, 35 did not vote, and five registered an abstention by voting both in favour and against.

My guess is that those who did not vote or abstained were actually for it and did not want to break party lines or face angry voters come election time. They had a good piece on The Daily Show the other day showing some of the "arguments" some of the Tories put forth and how they were nothing like what the Republicans act or believe.
